What is 3.37 as a percent?

To write 3.37 as a percent have to remember that 1 equal 100% and that what you need to do is just to multiply the number by 100 and add at the end symbol % .

3.37 * 100 = 337%

And finally we have:

3.37 as a percent equals 337%

Answer:

337%

Step-by-step explanation:

3.37x100=337

Answer:

24, 12, 10, 15, 10, 22, 12

mean:  7

median: 12

mode:  12

Range: 14

Step-by-step explanation:

Answer: Mean=15, Median=12, Mode=10 and 12, Range=14

Step-by-step explanation:

Data:

Numbers: 10, 10, 12, 12, 15, 22, 24

Mean: x, Median: x, Mode: x, Range: x

Step One, Find the Mean by adding all of the numbers and dividing them by the number of numbers

10+10+12+12+15+22+24=105/7=15

Mean=15

Reason: By adding all of the numbers together and dividing them by the number of numbers, you can find the mean because that is the method on finding the mean.

Step Two, Find the Median(middle) by finding the number in the middle

10, 10, 12, 12, 15, 22, 24

Median=12

Reason: Since the median is the number in the middle, 12 would be the median since it is the number in the middle of the array of numbers.

Step Three, Find the mode by finding the number that show up the most

10, 10, 12, 12, 15, 22, 24

Mode=10 and 12

Reason: Since mode is finding the number that shows up the most, 10 and 12 would be the answer for that reason and that they show up the same number of times in the array of numbers.

Step Four, Find the range by subtracting the biggest number by the smallest

24-10=14

Reason: Since to find the range you have to subtract the biggest number(24) by the smallest(10) the answer has to be 14 because that us the answer to 24-10.

I hope this helps!

Answer:

-37/6

Step-by-step explanation:

Answer:

yn +y -xn

Step-by-step explanation:

Mean= sum of numbers ÷number of numbers

x= sum of n numbers ÷n

Multiply both sides by n:

xn= sum of n numbers

sum of n numbers= xn -----(1)

Let the number added be a.

After a has been added,

y= (sum of n numbers +a) ÷(n+1)

Multiply both sides by (n +1):

y(n +1)= sum of n numbers +a

sum of n numbers= y(n +1) -a -----(2)

Substitute (1) into (2):

xn= y(n +1) -a

Expand:

xn= yn +y -a

a= yn +y -xn

Let's check!

Let the numbers be 1, 2, 3 and 4.

mean, x= 10 ÷4= 2.5

n= 4

Let the new number added, a, be 7.

a= 7

mean, y= 17 ÷5= 3.4

a= yn +y -xn

a= 3.4(4) +3.4 -2.5(4)

a= 7

Thus, the expression is true.

Answer:

Primer hermano = x = 16 años

Segundo hermano = y = 9 años

Step-by-step explanation:

Representemos sus edades como:

Primer hermano = x

Segundo hermano = y

Dos hermanos tienen 7 años de diferencia

= x - y = 7

x = 7 + y

La suma de los cuadrados de sus edades es 337.

x² + y² = 337

Sustituyendo

(7 + y) ² + y² = 337

Cuadrado

(7 + y) (7 + y) + y² = 337

49 + 7y + 7y + y² + y² - 337 = 0

2y² + 14y - 288 = 0

Paso 1: Factoriza el lado izquierdo de la ecuación.

2 (y − 9) (y + 16) = 0

Paso 2: Iguala los factores a 0.

y - 9 = 0 o y + 16 = 0

y = 9 o y = −16

Por tanto, y = 9 años

x = 7 + y

x = 7 + 9

x = 16 años

Primer hermano = x = 16 años

Segundo hermano = y = 9 años

(B) An uncontrolled experiment.

Step-by-step explanation:

In the case of an uncontrolled experiment here all participants are provided the similar treatment and there should be no comparison oppose to any group i.e. controlled

Since in the given situation, there are similar diets are provided to 20 volunteers and it can be that the  cholesterol level is decreased after particular time period,

Hence, it is an uncontrolled experiment.

Thus, option B is correct.

Answer:

9 hours

Step-by-step explanation:

We can use a ratio to solve

247 dollars       171 dollars

---------------- = -------------

13 hours             x hours

Using cross products

247* x = 13*171

247x =2223

Divide each side by 247

247x/247 =2223/247

x=9

Answer:

4 y + 3

Step-by-step explanation:

y = -3/4

d/dy((2 y + 1)^2 - 4 y^2 + 2) = 4

Indefinite integral:

integral(2 - 4 y^2 + (1 + 2 y)^2) dy = 2 y^2 + 3 y + constant

Given:

The graph of a polynomial.

To find:

The number of roots of the polynomial lie between x = -4 and x = 3.

Solution:

From the given graph it is clear that the graph is a downward U-shaped curve. It means the given graph represents a quadratic polynomial.

The graph of the polynomial is below the x-axis immediate before x=-2 and above the x-axis immediate after x=-2. It means the graph intersect the x-axis at x=-2.

The graph of the polynomial is above the x-axis immediate before x=2 and below the x-axis immediate after x=2. It means the graph intersect the x-axis at x=2.

Since the graph of the polynomial divides the x-axis two times between x = -4 and x = 3, therefore the two roots of the polynomial lie between x = -4 and x = 3.

Answer:

119cm

Answer:

(d) Using the commutative property

Step-by-step explanation:

Given

The above steps

Required

Which is not part of the process

We have:

[tex]5(2x-8)= 20[/tex]

[tex]10x - 40 = 20[/tex]

[tex]10x - 40+ 40 = 20 + 40[/tex]

[tex]10x = 60[/tex]

[tex]\frac{10x}{10} = \frac{60}{10}[/tex]

[tex]x = 6[/tex]

Comparing the above steps with the given list of options, we can see that the commutative property is not applied at all.

Other properties are:

[tex]5(2x-8)= 20[/tex] ---- Distributive

[tex]10x - 40+ 40 = 20 + 40[/tex] ---- Like terms

[tex]\frac{10x}{10} = \frac{60}{10}[/tex] --- Isolating the variable

Answer:

x = 3/2

Step-by-step explanation:

x- 3/4 + 2/3 = 17/12

x = 17/12 + 3/4 -2/3

x = 3/2

Answer:

Step-by-step explanation:

The x-coordinate of the point that divides the line segment will be -2. Then the correct option is B.

Let A (x₁, y₁) and B (x₂, y₂) be a line segment. Then the point P (x, y) divides the line segment in the ratio of m:n. Then we have

x = (mx₂ + nx₁) / (m + n)

y = (my₂ + ny₁) / (m + n)

The two endpoints are (-6, -2) and (8, -9). And m: n = 2: 5. Then the value of the x-coordinate is calculated as,

x = (2 · 8 + 5 · -6) / (2 + 5)

x = (16 - 30) / (7)

x = - 14 / 7

x = - 2

The x-coordinate of the point that divides the line segment will be -2. Then the correct option is B.

Step-by-step explanation:

When theres a triangle with a right angle you need to make in a rectangle and divide it by 2

Answer:

In order to find the area of a triangle, you need to use the formula [tex]\frac{1}{2} bh[/tex]. Substitute the known values into the formula and solve the equation.

Step-by-step explanation:

The formula to calculate the area of a triangle is [tex]\frac{1}{2} bh[/tex], where [tex]b[/tex] represents the length of the triangle's base, and [tex]h[/tex] represents the length of the triangle's height. Since [tex]b[/tex] and [tex]h[/tex] are variables that have different values in regards to different triangles, that means you should substitute the known/given values of each variable into the formula and solve the equation.

Answer:

Length & Breadth could be : 4 meters , 5 meters

Step-by-step explanation:

Border, ie perimeter measurement of Rectangle = 2 ( Length + Breadth )

So, 2 (Length + Breadth) = 18

Length + Breadth = 18 / 2

Length + Breadth  = 9

So, sum of length & breadth must be = 9.

(L, B) = (2,5) ; (2,8) ; (2,9) and (3,5) ; (3,8) ; (3,9) don't satisfy this condition. (4,5) ; (4,8) also don't.

(L, B) = (4,5) satisfy it. As sum 4 + 5 = 9.

Answer:

320 cm² or 264 cm²

Step-by-step explanation:

first, the rectangular face area is 4 faces at 8 x 6 = 192 cm²

the 2 square faces will be either 8 x 8 or 6 x 6.

If 8 x 8, then the SA will be 192 + (2 x 8 x 8 ) = 320 cm²

If 6 x 6, then the SA will be 192 + (2 x 6 x 6 ) = 264 cm²
